Web Server (IIS) role service provided in IIS 7.5

Internet Information Service (IIS) 7.5 is a web server in Windows 7 (IIS) and a web server in Windows Server 2008 R2. The Web server is redesigned in IIS 7 so that you can customize the server by adding or deleting modules to meet your specific needs. The module is a unique function used by the server to process requests. For example, IIS uses the authentication module to authenticate client creden。 and uses the cache module to manage cache activities.

Windows Server 2008 R2 provides all the IIS functions required to support web content bearer in the production environment. Windows 7 also provides the IIS function, but the available function depends on the version of Windows 7. IIS in Windows 7 is ideal for users who want to build and test web applications.

Available IIS 7.5 role services

The tables in this section show the availability of role services and IIS functions in each version of Windows 7 and Windows Server 2008 R2.

The availability of these features will be described in the following ways:

• Default Value: When you install IIS on your computer, this function is selected by default. However, if you do not need this function, you can choose not to install it.

• Available: this function is available, but it is not selected by default when you install IIS on your computer. If necessary, you can install this function.
• Unavailable: this function is unavailable and cannot be installed when IIS is installed.

Remarks
When installing Windows Server 2008 R2, you can install "server core". This method installs Windows Server 2008 R2 in the form of a minimal Server installation. For example, this type of installation does not install the traditional Windows interface, so you must configure the server through a command prompt.

Common HTTP Functions

Function Name/Description	Windows Server 2008 r2	Windows 7 Ultimate, professional, and Enterprise	Windows 7 Home Premium	Windows 7 Home Basic and starter
Static content "Static content" allows web servers to publish static Web file formats, such as HTML pages and image files. Use static content to publish files on the web server that users can view in the Web browser.	Default Value	Default Value	Default Value	Unavailable
Default document The "Default document" allows you to configure the default file for the Web server to return when the user does not specify a file in the URL. The "Default document" allows users to access your website more easily and conveniently.	Default Value	Default Value	Default Value	Unavailable
Directory Browsing "Directory browsing" allows users to view the contents of directories on the Web server. When you do not specify a file in the URL or disable or configure the default document, use "directory browsing" to provide a list of all directories and files automatically generated in the directory.	Default Value	Default Value	Default Value	Unavailable
HTTP Error With HTTP errors, you can customize the error messages returned to your browser when the web server detects a fault. HTTP errors can provide a better user experience when users encounter error messages. Please consider providing users with email addresses that can help them solve the problem.	Default Value	Default Value	Default Value	Default Value
HTTP redirection HTTP redirection supports redirecting user requests to specific targets. When you want customers who may use a URL to actually stop at another URL, use HTTP redirection.

CGI The Common Gateway Interface (CGI) defines how the Web server transmits information to an external program. A typical purpose is to use a web form to collect information and then pass the information to the CGI script to be sent to another location by email. As CGI is a standard, you can use a variety of programming languages to write CGI scripts. The disadvantage of using CGI is the performance overhead.	Available	Available	Available	Unavailable
ISAPI extension Internet Server Application Programming Interface (ISAPI) Extension supports dynamic web content development using ISAPI extension.

If these passwords are intercepted, it will be very easy to decrypt them. Use SSL with basic authentication.	Available	Available	Available	Unavailable
Windows Authentication Windows authentication is a low-cost authentication solution for internal websites. This authentication scheme allows administrators in Windows to use the domain infrastructure to authenticate users. If you must authenticate your website from the firewall and proxy server, do not use Windows authentication.	Available	Available	Unavailable	Unavailable
Digest Authentication Digest Authentication works by hashing the password and sending it to the Windows Domain Controller for authentication. When you need higher security than basic authentication, consider using digest authentication, especially, if you have to authenticate your website from the firewall and proxy server, you should consider digest authentication.	Available	Available	Unavailable	Unavailable
Client certificate ing Authentication Client certificate ing authentication uses client certificates to authenticate users. The client certificate is a digital ID from a trusted source. IIS uses client certificate ing to provide two types of authentication. This type uses Active Directory to provide one-to-one certificate ing across multiple web servers.
